Thank-you this is so much help, I am only confident with dandelions, which we have loads on our garden lol And I have been getting them blackberries.

My mate who is a Parks Manager is going to help me out identifying some plants for me

I think that this is by far the best way to learn what's out there.
It can open a door to a life long deeper appreciation, & love of wild life, enriching our lives.

My own background is an upbringing in the country when we were encouraged to identify the local wild plants & trees in primary school. It was also the norm for us to forage for our bunnies as children under supervision.
It led to a life long interest, but I'm not a botanist with the skills to identify all the UK plants to species level.

I try to recommend the plants which are easier to identify, as long as you check that the shape of the leaves & veins in the leaves are truely identical. Flowers and seed heads are helpful too but mot always present.

In spring, young plants can be more difficult to identify, especially those which mature into tall spikes & start as rosettes at ground level.

I commend Webble's choice of toxic plants. They include seriously toxic plants which we all need to be able to identify, & remove if buns could access them.
There are many other toxic plants which should not be fed to bunnies but a small nibble won't do any harm.
Those which are recommended as safe, can be fed regularly to bunnies.

I'm deeply moved & delighted by all your positive responses.

For those who rightly find wild plant identification too risky, may I suggest that you can also grow many kitchen herbs both for your bunnies as well as adding flavour & interest to human food.
